Weighted vs Unweighted CGPA: What’s the Difference?
When universities calculate academic performance, they often use either a weighted CGPA or an unweighted CGPA system. Understanding the difference helps students interpret their results correctly and calculate grades more accurately.
If your courses have different credit hours, you are most likely using a weighted CGPA system. You can easily calculate it using this tool:

What Is Weighted CGPA?
A weighted CGPA considers the credit hours of each course when calculating the final grade point average. Courses with more credit hours contribute more to the final CGPA.
Weighted CGPA Formula
CGPA = Σ (Grade Point × Credit Hours) ÷ Total Credit Hours
This formula ensures that subjects with heavier academic workload influence the CGPA more strongly.
Example of Weighted CGPA
| Subject | Credit Hours | Grade Point | Credit × Grade |
|---|---|---|---|
| Mathematics | 4 | 9 | 36 |
| Physics | 3 | 8 | 24 |
| Programming | 4 | 7 | 28 |
Total Weighted Points = 88
Total Credits = 11
CGPA = 88 ÷ 11 = 8.0
Because mathematics and programming have higher credit hours, they impact the final CGPA more than other courses.
What Is Unweighted CGPA?
An unweighted CGPA treats every course equally regardless of credit hours. Each subject contributes the same amount to the final average.
Unweighted CGPA Formula
CGPA = Total Grade Points ÷ Number of Subjects
Example of Unweighted CGPA
| Subject | Grade Point |
|---|---|
| Mathematics | 9 |
| Physics | 8 |
| Programming | 7 |
Total Grade Points = 24
CGPA = 24 ÷ 3 = 8.0
In this system, all courses carry equal importance, even if some courses require more workload.
Key Differences Between Weighted and Unweighted CGPA
| Feature | Weighted CGPA | Unweighted CGPA |
|---|---|---|
| Credit Hours Considered | Yes | No |
| Course Difficulty Impact | Higher | Same for all courses |
| Calculation Method | Credit-based formula | Simple average |
| Accuracy | More precise | Less precise |
| Used by Universities | Very common | Less common |
Why Universities Prefer Weighted CGPA
Most universities use weighted CGPA systems because they reflect the actual academic workload of each course.
For example:
- Engineering subjects often have 4–5 credits
- Elective courses may have 2–3 credits
A weighted system ensures the harder or more intensive courses influence the final CGPA appropriately.
How to Calculate Weighted CGPA Online
Manually calculating weighted CGPA can take time, especially if you have many courses with different credit hours.
A faster option is to use an online CGPA calculator with credits, where you simply enter:
- Subject name
- Credit hours
- Grade
The tool automatically calculates the weighted CGPA, total credits, and grade contribution.

When Unweighted CGPA Is Used
Unweighted CGPA systems are often used in:
- Some high school grading systems
- Simplified academic evaluations
- Programs where all courses have equal weight
However, most universities prefer credit-based CGPA calculations because they provide a more accurate picture of academic performance.
Final Thoughts
Both weighted and unweighted CGPA systems measure academic performance, but weighted CGPA provides a more realistic evaluation because it considers course credit hours.
If your university assigns different credits to courses, your CGPA should always be calculated using the weighted formula.
